To all whom z't may concern.

Be it known that I, STEPHEN a subject of the King of Grdeat Britain andireland, rcsidin Lane; London, E. C., Eng and, have invented certainlnew and useful Improvements Relating to IIurnace-Settings for' the IDestructive Distillation of Coal or other Carbonaceous Substances, ofwhich the followigis'a specification. .y i U This invention relates tofurnace' settings for the destructive'distillation ot'V coal or othercarbonaceous substances and especially 'to that type of furnace at thetop and of an oblong wardly toward the bottom are set 1 n a known'settings where vertical retorts are employed which are chargeddischarged at the bottom, and where the retorts areA of an oblongsection; and thev inventio'n has for its object to effect the heating of'the retorts uniformly and with eiciency and in such manner that thetemperature conditions throughou precisely regulated according' to"acter f the residue and by-products re- The respective retortsWhi'clilaie formed cross section and ytap'ered outmanner between seriesof horizontal parti- .,-to traverse the lengt chamber lto and fro socharged.

ltions which 4form a vertical series of horizontal chambers besideandbetween the re spectiveretorts and extend from one wall of the settingto the other. These chambers are provided according to the inventionwith two thin vertically disposed partitions by `which a centralcombustion spaccis formed between themby which the heating gases arecompelled to take a tortuous nath, that is h of thehorizgntal thatV thusthe heating space besidey the". retorty before being dis-` Two' suchthin are provided in eachV horizontal chamber so th'atthusa mixture ofgasani air'inay pass between the respective two partitions of eachzsetand on reaching the end'of the partitions opposite to that-at which themixture of gas and air is admittedj, the gases may y return and pass onthe outer side of each of the .partitions along' the lateral spaces between the respective partitions and the adj acent retorts. The heatingrgases are thus di- 'rected in contact with theouter surface of Newcomerat 39 Mincing f may be he charvertical partitions Vspective vertical 4Av peoioation of Letters Tatent.

the retort and the circulation of the gasesV takes place withinr oneplane.

According to the invention moreover, I provide adjacent the series-ofretorts, a. series of substantially vertical exhaust iiuescorrespondingin number to the number ofA horizontal chambers of therespective vertical series.

.A recuperator or regenerator is provided `advantageously beneath thesetting and pas sages are fprmed or a chamber is provided 1n the settingthrough which the'air may pass before entering'the respective vertical1r iiues, the construction of thechamber or passages being such that thewalls Vthereof areheated by the exhaustgases passing out: orli'nstead aregencrator may beprovided 1 n which the fiow of air and the exhaustgases maybe reversed-in the regenerator.

understood that the waste gases will always pass through the verticalseries of exhaust dues and the air through the vertical series furnacesetting taken on the line F of Flg. 2,

Fig. 2 is a vertical section on the line A, of Fig. 1, r

Flg. 3 is a compound vertical section on Vthe line C, D of Fig. 1, and

Fig. 4; is a vertical section on the line Gr, H of Fig. 1.

` In carrying the invention into .reect according to ione constructionvI provide a series of vertical retorts a of oblong section within asetting in the lower part of which a regenerator or recuperator b1 isprovided,

I provdebeside and between the reretorts a vertical series of horizontalpartitions b without necessarily .In such a modification, however, itwill be L which form a central combustion space comparativelyWideextending the length of the retort into which at one end the supplyof 'gas and air passes for combustion therein.

The vertical partitions, however, extend at the other end of the heatingchamber opposite to that at which the gas and air enter a little shortof the extreme end wall so that thus a space is formed at that end 4intowhich the gases may discharge and return in the opposite directionthrough the nar-V rower lateral spaces c1 formed by the partitions oneach sideof the central space.

' A damper block c2 be provided at the end of the heating chamber atwhich the gases discharge from the central vcombustion s ace. Suchdamper blocks present their lnclined faces to the current of gases sothat thus the inclined faces serve to deiiect the gases while the damperblock serves at the same time to regulate the outflow according to theposition in which it is pf z d with respect to the ends o f thepartitior c.

The respective vertical partitions c referred to are provided of thesame refractory material as that of which the horizontal partitions bare provided or they may be formed asa tube of a square or othersuitable section so as to divide the heating chamber by substantiallyvertical walls into three spaces on`each side of the retorts.

The gas may be led into the central combustion space throu h ahorizontal pipe d extending through t e setting at one side,

lthe gas pipe for each chamber of the vertical series being connected toa substantially' Y vertical service pipe d* mounted on the exterior wallof the setting. An' air passage e is also provided horizontall in thesetting for leadingV air to each o the combustion spaces, and the airpassage foreach heating chamber of the vertical series communicates withthe respective vertical air eouslj7 may be led 1r fiues f from each sideinto the respective yhorizontal air passages e, and the ports g throughwhich the air is admitted to the respective horizontal passages may beregulated by means of sliding dampers g1 or other suitable means.'

As Ithe greater thickness of the charge of coa'lin'the'lower ends of thetapered retorts necessitates rthe expenditure of more heat indist'ill'atio'n'- than at the upper and thinner portion .of the charge,the gas pipes d of the rovided of lower -h eatin chambers are reatercapaclty than those o the upper eating chambers. p

outer Wall ofthe casing of angular form may` the sald horizontal Thelhorizontal air passages e may be formed as tubes of metal or' the may beformed of refractory material, while the-corresponding gas pipe for eachair passage may pass centrally therethrough and the horizontal airpassage may extend to the hmay be mounted. v

A series of vertical exhaust lines i is built in the setting adjacentthe heating cham: bers, and ports j are provided in the intermediatewall through .which the gases may discharge from the lateral spaces 'ofthe lheatin chambers Ainto the adjacent exhaust iue.` twill beunderstood that in such an arrangement the series of vertical air uestherespective exhaust and air fluesare arranged in line.

With respect to other constructional features the construction andarrangement of the furnace setting is substantially the same as thatdescribed in the specification filed pursuant to the prior applicationNo.'53,631 of 1915.

I claim:-

1.
